[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-3, an embodiment provided by the present utility model:
[0020] A flexible PCB board connector test fixture, including a fixture upper frame 1 and a fixture bottom box 2. The fixture upper frame 1 is placed on the fixture bottom box 2. A fixture upper press 4 is arranged inside the fixture upper frame 1. A corresponding fixture carrier 5 is arranged on the fixture bottom box 2 under the fixture upper press 4. A USB test structure 3 corresponding to the fixture carrier 5 is arranged at the rear side of the fixture bottom box 2.
[0021] During operation, the staff places the PCB board on the fixture carrier 5 and fixes it through the fixture upper press 4 inside the fixture upper frame 1. At the same time, the USB test structure 3 is used to push the USB interface forward, so that the PCB board and the USB interface are docked and communicate to test the PCB board.
[0022] The USB test structure 3 includes a USB push-in bed 31, a forward push cylinder 32, and a USB fixed clamping position 33. The USB fixed clamping position 33 is placed on the USB push-in bed 31, and the forward and backward movement of the USB push-in bed 31 is controlled by the forward push cylinder 32. Both sides of the USB push-in bed 31 are movably connected to the fixture bottom box 2 through a push-in structure 6. The push-in structure 6 includes a guide post fixing plate 61 that fixes both sides of the USB push-in bed 31. One side of the guide post fixing plate 61 is fixed to the USB push-in bed 31 through a guide post 62, and the other side is movably placed inside the fixture bottom box 2.
[0023] In the USB test structure 2, the forward push cylinder 32 is used to push the USB push-in bed 31, so that the USB interface in the USB fixed clamping position 33 fixed on the USB push-in bed 31 can quickly dock with the PCB board on the fixture carrier 5. The USB push-in bed 31 is movably connected to the fixture bottom box 2 through the push-in structure 6 and moves back and forth inside the fixture bottom box 2 through the guide post fixing plate 61 to realize the forward and backward movement of the USB push-in bed 31.
[0024] There are balls 63 tested in the inner cavity of the fixture bottom box 2. The balls 63 are in rolling connection with the guide post fixing plate 61. The design of the balls 63 makes the back-and-forth push of the guide post fixing plate 61 smoother.
[0025] The fixture upper press 4 includes a lifting hydraulic machine 41, a top plate 42, a pressing column 43, and guide posts 44 on both sides. The lifting hydraulic machine 41 is placed in the fixture upper frame 1. The lifting hydraulic machine 41 is connected to the top plate 42 below. A pressing column 43 corresponding to the position of the USB fixed clamping position 33 is arranged below the top plate 42. The top plate 42 is slidably sleeved with the guide posts 44. After the PCB board is placed on the fixture carrier 5, through the lifting of the lifting hydraulic machine 41, the pressing column 43 under the hydraulic lift 41 is pushed to press and fix the PCB board, avoiding product displacement when docking with the USB interface and avoiding the occurrence of docking problems.
[0026] Therefore, when the device is working, the circuit control system in the jig bottom box 2 is used to control the jig upper press 4 in the jig upper frame 1 and the USB test structure 3 in the jig bottom box. In the circuit control system, the operation of the circuit control system is controlled by the start key 7 on the surface of the jig bottom box 2, the test is controlled by the test button 8, and the test results are displayed by the liquid crystal display screen 9. In addition, heat dissipation holes 10 and handles 11 for easy handling are provided on both sides of the jig bottom box 2;
[0027] After the PCB board is placed on the jig carrier 5, the lifting hydraulic machine 41 of the jig upper press 4 starts to work, driving the top plate 42 and the pressing column 43 to press downwards, so that the pressing column 43 presses the PCB board placed on the jig carrier 5 and fixes it. Then, the USB push bed 31 in the pushing mechanism is pushed forward by the forward push cylinder 32, so that the USB interface fixed at the USB fixing position 33 on the USB push bed 31 is docked with the PCB board and the PCB board is tested;
[0028] The guiding column 44 in the jig upper press 4 has the functions of guiding, positioning and limiting.
